Subject: [PATCH 0/2] KASAN support for RISC-V
Date: Wed, 7 Aug 2019 15:19:13 +0800	[thread overview]
Message-ID: <cover.1565161957.git.nickhu@andestech.com> (raw)

KASAN is an important runtime memory debugging feature
in linux kernel which can detect use-after-free and out-of-
bounds problems.

There are two patches in this letter:
1. Porting the memmove string operation.
2. Porting the feature KASAN.

Nick Hu (2):
  riscv: Add memmove string operation.
  riscv: Add KASAN support
